Enterprise AWS cloud migration and managed services, Well-Architected delivery from day one
TantranZm delivers AWS cloud migration, landing zone architecture, and ongoing managed services for enterprise organisations, following the AWS Well-Architected Framework across all five pillars. ISO/IEC 27001:2022 governs every data handling decision.
What does enterprise AWS cloud consulting cover and what does TantranZm deliver?
Enterprise AWS consulting covers the end-to-end process of migrating on-premise and legacy workloads to Amazon Web Services, designing production-grade cloud architectures using the AWS Well-Architected Framework, and establishing the governance, security, and cost management frameworks required to operate at enterprise scale. TantranZm delivers structured migration programmes using the AWS Migration Factory methodology, assess, mobilise, migrate, optimise, followed by optional managed operations under SLA. All engagements are governed under ISO 9001:2015 quality management and ISO/IEC 27001:2022 information security certification.
AWS service capabilities
From initial migration assessment through to ongoing managed cloud operations, covering the full AWS service estate.
Cloud Migration
Structured migration using the 6R framework (Rehost, Replatform, Repurchase, Refactor, Retire, Retain) across assessment, mobilise, migrate, and optimise phases. Application discovery, dependency mapping, cutover planning, and post-migration validation included.
Infrastructure Architecture
Landing zone design, multi-account governance using AWS Control Tower and Service Control Policies, VPC architecture, and infrastructure as code with Terraform and AWS CDK, aligned to the AWS Well-Architected Framework from day one.
Database & Data Services
RDS, Aurora, DynamoDB, Redshift, and OpenSearch deployment, migration, and optimisation. Includes schema migration, performance tuning, read replica configuration, and backup/DR strategy for enterprise data estates.
Serverless & Modern Architecture
Lambda function development, API Gateway configuration, Step Functions orchestration, EventBridge event-driven architecture, and containerised workloads on ECS/EKS for scalable, cost-efficient application delivery.
Security, Compliance & IAM
IAM policy governance, AWS Security Hub, GuardDuty, CloudTrail, and Config implementation. ISO/IEC 27001:2022 aligned security controls, encryption at rest and in transit, and compliance posture reporting for enterprise audit requirements.
FinOps & Cost Optimisation
AWS Cost Explorer analysis, Reserved Instance and Savings Plans strategy, right-sizing recommendations, Spot Instance adoption, and ongoing cost governance. Structured FinOps practice aligned to CloudCost Optimization Framework principles.
AWS Migration Factory methodology
A structured four-phase methodology that reduces migration risk, accelerates delivery, and ensures every workload is production-ready before cutover, not after.
Assess
2–4 weeksApplication discovery and inventory, dependency mapping, migration wave planning, TCO analysis vs on-premise, and AWS Landing Zone design.
Mobilise
3–6 weeksLanding zone build, network connectivity (VPN/Direct Connect), IAM framework, governance guardrails via Control Tower, and migration tooling setup.
Migrate
8–16 weeks per waveWave-based workload migration using AWS MGN, Database Migration Service, and application-specific tooling. Cutover planning, testing, and rollback procedures per wave.
Optimise
OngoingPost-migration right-sizing, Reserved Instance purchase, performance benchmarking, security posture review, and ongoing managed operations handover.
6R Migration Decision Framework
Five pillars of production-grade architecture
Every TantranZm AWS architecture is reviewed against all five Well-Architected pillars, not just the security and cost dimensions that are easiest to demonstrate.
Operational Excellence
Runbook automation, CloudWatch dashboards, alarm thresholds, incident response procedures, and continuous improvement cycles.
Security
IAM least-privilege, encryption, GuardDuty threat detection, Security Hub posture scoring, and CloudTrail audit logging.
Reliability
Multi-AZ and multi-region architecture, Auto Scaling groups, Route 53 health checks, and RTO/RPO-defined disaster recovery.
Performance Efficiency
Instance right-sizing, serverless adoption, caching (ElastiCache/CloudFront), and load testing against production workload patterns.
Cost Optimisation
Savings Plans, Reserved Instances, Spot adoption, resource scheduling, S3 Intelligent-Tiering, and monthly cost governance reviews.

Security & Governance
Post-migration managed cloud operations
Migration is day one. TantranZm's managed services model covers the ongoing security, cost, compliance, and operational work that keeps your AWS environment production-grade.
24/7 Infrastructure Monitoring
CloudWatch metric monitoring, log aggregation, anomaly detection alerting, and on-call escalation. SLA-backed incident response with defined P1/P2/P3 response times.
Security Patching & Compliance
Automated patch management via AWS Systems Manager, monthly vulnerability scanning, Security Hub posture reporting, and quarterly ISO 27001 evidence collection.
FinOps & Cost Governance
Monthly cost review, anomaly alerting, Reserved Instance utilisation tracking, right-sizing recommendations, and savings realisation reporting against agreed targets.
Change & Release Management
Change advisory board process integration, CloudFormation/Terraform change governance, blue/green deployment support, and quarterly architecture review cadence.
AWS Services FAQs
What AWS services does TantranZm specialise in?
TantranZm delivers end-to-end AWS services including cloud migration, infrastructure architecture using the AWS Well-Architected Framework, database services (RDS, Aurora, DynamoDB, Redshift), serverless solutions (Lambda, API Gateway), security and compliance, and ongoing cost optimisation. Our engineers hold hands-on expertise across EC2, S3, ECS/EKS, CloudFront, and the wider AWS ecosystem.
Can TantranZm migrate our on-premise workloads to AWS?
Yes. We follow a structured four-phase approach, assess, mobilise, migrate, and optimise, covering application discovery, dependency mapping, workload prioritisation, and cutover planning to minimise downtime and business risk during the migration.
Does TantranZm provide managed AWS support after go-live?
Yes. Our managed services cover 24/7 infrastructure monitoring, cost governance, security patching, incident response, and continuous optimisation to ensure your AWS environment remains secure, performant, and cost-effective post-migration.
How long does a typical enterprise AWS migration take?
Timelines vary based on estate size and complexity. A mid-market migration typically runs 8–16 weeks from initial assessment to production go-live. Large-scale, multi-account programmes can extend to 6–12 months and are delivered in phased waves.
Does TantranZm follow the AWS Well-Architected Framework?
Yes. All TantranZm AWS engagements are aligned to the AWS Well-Architected Framework's five pillars, operational excellence, security, reliability, performance efficiency, and cost optimisation, to ensure architectures are production-grade from day one.
